How to delete rows of a matrix when one column contains a dummy variable

I need to resize my data sample. I have a data matrix that looks like:

Data = [lnwages educ exp expsq black married]

Each column of Data is a 13,000 x 1 vector. Hence data is a 13,000 x 6 matrix. Educ, black, married are dummy variables (0's or 1's).

How can I delete all the rows where married = 1? This would change my data so that it only contains unmarried individuals and their corresponding wages, educ, etc.. Married is the sixth column of data.

I would like the output in a new matrix. Call it newdata.

Thanks so much for your help.

idx=Data(:,6)~=1
newdata=Data(idx,:)

Great Answer! Would you mind explaining what's going on here? I'm an Econ grad student and this command will most likely change my life.

Example

x=[1 2 3 4 5]
idx=x>2  % where x is >2 the result is 1, elswhere it's 0
out=x(idx)  % is logical indexing, will ignoàre 0 indices.
